Sony exec in bomb scare amid PlayStation hack attack

UNDER ATTACK: Sony has been keeping gamers up to date on the Playstation blog.

Sony's PlayStation Network was taken down by hackers and the FBI was investigating the diversion of a flight carrying a top Sony executive amid reports of a claim that explosives were on board.

The company said in a posting on its PlayStation blog today that no personal information on the network was accessed in a denial of service-style attack, which overwhelmed the system with heavy traffic.

"We will continue to work towards fixing this issue and hope to have our services up and running as soon as possible," it said.

Yes. My plane was diverted. Not going to discuss more than that. Justice will find these guys.

Meanwhile, a plane carrying Sony Online Entertainment President John Smedley was diverted on Sunday (local time), Smedley said in a post on Twitter.

A group called Lizard Squad sent a message through its Twitter account to American Airlines saying Smedley's flight had explosives on board, according to a report by USA Today. The group also used Twitter to claim credit for the network attack, the newspaper said.

USA Today reported that the Dallas/Fort Worth flight to San Diego was diverted and landed safely in Phoenix.

A PlayStation spokeswoman in the United States said the diverted flight was being handled by the FBI and had no comment. An FBI spokesman had no immediate comment.

Sony is hoping its PlayStation network, with 52 million active users, can serve as a centrepiece of its plans to rebuild its business after years of losses in its flagship electronics operations.

The network business has been hit by attacks before, with a security breach in 2011 dealing a major blow to plans at the time for a looser network designed to allow for the connection of a range of Sony devices.
